Description

Technical Field

[0001] The present invention relates to the field of rock specimen production, and in particular to a device and method for producing a rock specimen with built-in holes. Background Art

[0002] Karst landforms are formed by the dissolution and precipitation of soluble rocks by groundwater and surface water, as well as gravitational collapse, collapse, and accumulation. This dissolution and erosion of soluble rocks by groundwater and surface water results in the development of numerous irregularly shaped caves, which negatively impact underground engineering within these landforms. With economic development, rock engineering construction within karst landforms in southwest China urgently needs solutions. However, the crack development patterns and failure characteristics of rock masses containing voids under stress failure are still unclear. Therefore, rock mechanics test specimens with embedded voids are urgently needed to analyze the experimental process under uniaxial or multiaxial stress.

[0003] Currently, the production of rock specimens with built-in holes is done manually, from batching, mixing, to compaction. This process is not only inefficient but also physically demanding. Inaccurate batching and mixing can also lead to uneven mixing. Furthermore, the rock specimens are exposed to dust, which can pose long-term health risks to the makers. Finally, during manual compaction, uneven force is applied to the specimens, leading to problems such as insufficient local strength and uneven appearance. These issues are particularly severe when producing large quantities of rock specimens. Summary of the Invention

[0061] The following takes the production process of a rock-like specimen as an example to provide the specific working process of the present invention: First, add the ingredients required for producing the rock-like specimen into the batching funnel 5, add the water required for mixing into the water spray controller, and set the mass of each required ingredient and water in the controller 1. Turn on the "Start" button of the controller 1, the batching motor 3 starts working, controls the rotation of the batching bracket 4, rotates the batching funnel 5 to the batching workbench, and the controller 1 controls the opening and closing mechanism 24 to sprinkle the ingredients into the mixing bowl 9 on the batching workbench. The electronic scale 6 is used to control the mass of the ingredients sprinkled from the batching funnel. When the mass of the first ingredient sprinkled reaches the mass set by the controller 1, the batching motor 3 works again, rotates the batching funnel 5 containing the next ingredient to the batching workbench, and performs the material sprinkling operation again. When all ingredients are sprinkled, the weighing is completed.

[0062] The mixing motor 7 starts to work and controls the mixing telescopic bracket 8 to rotate 90° counterclockwise, rotating the mixing bowl 9 to the mixing workbench. The controller 1 controls the stirring telescopic rod 22 to make the stirring bracket 11 reach the appropriate height. At this time, the stirring motor 16 starts and cooperates with the stirring claw 12 to evenly mix the different ingredients in the mixing bowl 9 on the mixing workbench. After the ingredients are evenly mixed, the controller 1 first controls the stirring telescopic rod 22 to rise, and then controls the mixing motor 7 to rotate the mixing telescopic bracket 8 90° counterclockwise, rotating the mixing bowl 9 to the water spraying workbench. The controller 1 controls the water spraying telescopic rod 23 to make the water spraying bracket 13 reach the appropriate height. At this time, the water spraying controller 15 starts to spray water from the water spraying head 14 into the mixing bowl 9 according to the water volume set by the controller 1.

[0063] After the water is added, the controller 1 controls the water spray telescopic rod 23 to rise, and then controls the mixing motor 7 to rotate the mixing telescopic bracket 8 90 degrees counterclockwise, and rotate the mixing bowl 9 to the mixing workbench. The controller 1 controls the stirring telescopic rod 22 to make the stirring bracket 11 reach a suitable height. At this time, the stirring motor 16 is started and cooperates with the stirring claw 12 to stir the ingredients in the mixing bowl 9 of the mixing workbench after adding water, so that the ingredients and water are fully mixed; after the rock-like specimen ingredients are made, the controller 1 controls the length of the stirring telescopic rod 22 for the first time, and delivers the mixing bowl 9 to the top of the rock specimen mold 20 of the hydraulic workbench.

The ingredients are sprinkled into the rock specimen mold 20 for the second time. The controller 1 controls the stirring telescopic rod 22 to retract for the second time and controls the vibration motor 19 for the second time to vibrate the filled ingredients until they are leveled. After the filling is leveled, the hydraulic motor 17 starts working to make the hydraulic rod 21 Compact the filler in the rock specimen mold 20 downward; while spreading the ingredients into the rock specimen mold 20, place prefabricated meltable ice cubes in the designated position of the specimen in the mold 20 in advance; repeat the above steps for the fourth time, and the initial rock-like specimen is completed; remove the rock specimen mold 20 from the hydraulic workbench, dismantle the mold 20, and place it in a standard curing room at 0°C for curing until the specimen is completely solidified; after the curing is completed, place the initial rock-like specimen in an oven and heat it to 25°C to completely melt the prefabricated ice cubes, thereby obtaining a rock specimen with built-in holes.
